Explain this statement-“Exports of frog legs have adverse effects on biodiversity.”

In Europe and North America, legs of frogs were used to increase the taste of the food. Many Asian Countries, Including India, used to export the legs of a frog. In the year 1983, India exported 36500 metric tonnes of frog legs. As a result, the number of frogs in the forest reduced very much, and the insects which were eaten by frog increased tremendously.
